INT 03 - CPU-generated - BREAKPOINT Desc: generated by the one-byte breakpoint instruction (opcode CCh) Notes: used by debuggers to implement breakpoints, such as MS-DOS DEBUG's G command also used by Turbo Pascal versions 1,2,3 when {$U+} specified return address points to byte following the breakpoint instruction called by Novell DOS 7 EMM386 after displaying an exception error message (GPF, illegal opcodes, etc.) and before waiting for user input called by QEMM-386 if the user presses 'I' (undocumented) when prompted after an exception error message SeeAlso: INT 01"CPU"
